I don’t know what to do. Please help me.

I’ve been dating my boyfriend for almost a year and a half now. Even when we first got together he talked about how he knew I was the one he wanted to marry. I thought that was what we both wanted, so when he got a job offer 12 hours away and wanted me to go with him, I kind of expected some kind of proposal or commitment type thing. Nothing happened. That was over 8 months ago. Now we’ve been living together for 3 months and he keeps telling me we’re not ready. His parents were divorced when he was young, so I understand that for him marriage is only a piece of paper, but to me it’s that commitment. His family keeps telling him to wait until he’s 30 to get married, but I’ve told him I don’t want to wait that long. I’ve told him I want to at least be engaged in the next 2 years. Over the last few months things have been difficult, so last night I finally asked him where he sees us in 3 years. He didn’t even mention an engagement or marriage or anything even similar. I don’t know what to do. It’s starting to feel like he’s moving further and further away from the idea of marrying me. I don’t want to keep feeling like I’m wasting my time. What should I do? Am I crazy for feeling this way?
